i.e. which end do I point at the middle pin of Pine's battery input? the gold end - or the end with two darker stripes (I can't tell what colour they are)?
hi, resistors are not 'directional' like a diode is. Put it in either direction, does not matter. The 10K resistor connects to the center pin, and runs to ground. The positive RED wire goes in VBAT+ and the black negative wire goes in VBAT-
What Mark said
And please don't tell us you can't tell the difference between red and black (as you said you were colour blind)... otherwise I'll start to cry knowing a pine64 is about to suffer it's demise (50/50 chance) :
Well, my generic 8000mah battery seems to be no-where near it's rated capacity - is lasting about half the time I would have liked (basically overnight). I had intended to make it so the pine64 was charged from solar when the sun was up, and run from the battery overnight, but the battery is only just making it overnight, so won't last long with that near total usage, and doesn't leave any room for the pine64 do actually do some work.... this was with the pine64 idling.
So much for 8000 / 300 = 26 hours (or 20 hours if you base it on a 400ma load). Either this battery is not up to spec (likely), and/or the pine64 is lying about it's power consumption (also possible). I'm getting 15 hours of runtime (and it saying 3% capacity when the power cuts back in!!!), so not happy jan! Maybe I'll have to strap on a second cell in parallel give it the capacity bump it needs. I'm liking the idea of using 18650 cells in holders... 5 or 6 of those at 2200mah should do the trick (and be about the same size as the pine64 to boot!
